A pin closure system, especially for use in securing the upper and lower frame plates of a radiation therapy treatment mask. An upper sleeve having an expansile portion is placed and engaged within a shaped fenestration of an upper frame plate, while a lower sleeve having an expansile portion is placed and engaged within a shaped fenestration of a lower frame plate. An axial pin is inserted spanning both sleeves, causing the expansile portions to expand radially, engaging the sleeves together and locking the plates together. The system may also be used to use a single pin to simultaneously lock the upper and lower frame plates together and to an external substrate, such as a treatment table for repeatable and highly accurate patient positioning.

A medical connector includes a body having a distal end, a proximal end, and a sidewall extending between the distal end and the proximal end, a helical thread extending radially outward from a surface of the sidewall and comprising a crest portion, flank portions, and a root portion with the flank portions connecting the root portion to the crest portion, and at least one micro-thread extending radially outward from the surface of the sidewall. At least a portion of the micro-thread is spaced apart from the helical thread.

The invention provides systems and methods for mounting a fuel system to a vehicle. In some embodiments, the invention provides systems and methods for mounting a fuel system comprising a fuel tank to a vehicle chassis using a bracket, which may be a multi-part bracket, and may be referred to as a drop and go bracket.

A universal mounting system is provided for use in connection with substantially any type of electronic equipment so was to reduce or substantially avoid the need for rail kids or other mounting assemblies that are its equipment specific for mounting equipment to racks. In one implementation, a uniform mounting system (101) includes a number of rail and slider assemblies (112). Each of the rail and slider assemblies includes a slider that is slightly mounted on a support rail. Each of the slider is includes mounting flange is and brackets for mounting the slider to a piece of equipment. The mounting flanges 116 that's collectively define a segmented vertical rail. A safety stop mechanism can be used to define very a offset figurations of the equipment with respect to a front end of the rack.

An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion having an inwardly facing annular groove orientated transverse to the central axis; a shroud concentrically mounted on the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the inwardly facing annular groove of the shroud-receiving portion of the body; the axially-buckled radially-extending annular protrusion of the shroud and the annular groove of the shroud-receiving portion of the body forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

An axle assembly for a vehicle includes an axle shaft having a bolt end and a lever end. The axle assembly includes a cam assembly coupled to the lever end of the axle shaft. The cam assembly includes a cam housing, a cam follower shaft coupled to the cam housing, and the cam follower shaft is located coaxially within the axle shaft. The cam follower shaft does not extend the full length of the axle shaft. The cam shaft is coupled to the cam follower shaft, and a lever is coupled to the cam assembly. The lever is rotatable from an open position to a closed position, and an angle of maximum rotation for the lever between the open position and the closed position is less than 180 degrees.

A ventilation hood is mounted to an underside of a cabinet, including a bottom panel and a lower support frame positioned above a cooking appliance, by first and second brackets secured below the cabinet at spaced positions aligned with outermost edge portions of the lower support frame and at least one fastener assembly secured to a front portion of the ventilation hood. Multiple embodiments are disclosed for the at least one fastener assembly, including tabs bent from a housing of the ventilation hood, feet threadably attached to the hood, mounting blocks including snap connectors, threaded fasteners, and pinned bolts.

In some embodiments, the invention provides systems and methods for mounting a fuel system comprising a fuel tank to a vehicle chassis using a bracket, which may be a multi-part bracket, and may be referred to as a drop and go bracket.

A method and device for a captive fastener assembly comprising of a fastener including a head and a shaft, the shaft comprising of a threaded section and an unthreaded section being interposed between the head and the threaded section. A standoff accommodating the fastener permanently fastened to the first surface and enabling the fastener to have an angular and circular motion within the standoff and fastening the first surface with the other surface by placing the surfaces together so that the fastener is substantially aligned with the receiving nut on the other surface for coupling, wherein a marginal offset for the alignment of fastener with the female part of the other surface is allowed.

A method for assembling at least two parts, connected by main and secondary definitive connections arranged in predetermined positions, includes: secondary definitive connections each housed in secondary definitive holes passing through the parts to be assembled, made independently of one another before the parts are assembled, main definitive connections each housed in main definitive holes passing through the parts to be assembled, made during the same operation while the parts are held in place by the secondary definitive connections.
